When modelling the linear motion of a magnet around a coil or other ferromagnetic materials in 3D, it seems that (1) moving mesh is requred for large motion; (2) magnetic field, no current interface is requred to enclose the identity pair so that continuity coupling only involves the magnetic scalar potential; (3) magnetic field interface is required for the domains with coil/current. The problem is: how to couple the magnetic field, no current interface with the magnetic field interfance. Without proper coupling, the two interfance just works separately. This coupling is automatic in rotating machinary.
